Jupiter now has at least 79 moons, the most for any known planet. But where did these newly discovered moons come from?
Titan is more than a billion kilometres from our Sun but occasionally it's shadow can be seen here on Earth, with the right technology. That's what scientists gathered in Western Australia to observe.
We could be exploring the oceans of Jupiter's and Saturn's icy moons in a couple of decades. Here's what we need to work out.

As the list of known planets beyond our solar system grows, the search for their moons is intensifying. One reason: they might hold the key to finding life elsewhere in the universe.
Pluto's moon Charon seems to have had a violent past, with icy volcanoes leaving huge fractures.
Space scientists have a busy decade ahead with plans to visit Jupiter, Mars, Mercury and other interplanetary bodies all on the cards.
Why the Breakthrough Listen project is a step in the right direction in our hunt for life beyond Earth.
